Unramified Reciprocal Polynomials and Coxeter Decompositions
نویسنده
چکیده
We classify certain automorphisms of an even unimodular lattice L with fixed irreducible and unramified characteristic polynomial. The question which automorphisms are conjugate to their inverses in the orthogonal group of L is investigated. 2000 Math. Subj. Class. 11H56, 11R06, 20F55.

متن کاملCoxeter Decompositions of Hyperbolic Tetrahedra
In this paper, we classify Coxeter decompositions of hyperbolic tetrahedra, i.e. simplices in the hyperbolic space IH. The paper together with [2] completes the classification of Coxeter decompositions of hyperbolic simplices.
متن کاملCoxeter Decompositions of Bounded Hyperbolic Pyramids and Triangular Prisms
Coxeter decompositions of hyperbolic simplices where studied in math.MG/0212010 and math.MG/0210067. In this paper we use the methods of these works to classify Coxeter decompositions of bounded convex pyramids and triangular prisms in the hyperbolic space IH.
متن کاملAtomic decompositions for tensor products and polynomial spaces
We study the existence of atomic decompositions for tensor products of Banach spaces and spaces of homogeneous polynomials. If a Banach space X admits an atomic decomposition of a certain kind, we show that the symmetrized tensor product of the elements of the atomic decomposition provides an atomic decomposition for the symmetric tensor product ⊗n s,μX, for any symmetric tensor norm μ. In addi...
